Description

A kind of composition being used to prepare high-pressure slip-casting molding mud and its use the combination The mud that object is prepared
Technical field
The present invention relates to ceramic manufacturing fields, and in particular to the preparation of injection forming mud.
Background technique
With the development of sanitary ceramics industry, in the production process of ceramics, high-pressure slip casting process accounts in the industry Than increasing, compared to low pressure molding, high-pressure molding has the characteristics that high-efficient, labor intensity is low.However, being molded into for gypsum What the material-mud of slurry can not adapt to the demand of high-pressure molding, especially mud eats slurry speed, determine high-pressure molding at Type period and production efficiency.Therefore the urgent need that there is the higher mud for eating slurry speed just to become Production of Ceramics for preparation.
Summary of the invention
It is an object of the invention to solve the problems of the prior art, one kind is provided and is used to prepare high-pressure slip-casting molding mud The composition of slurry and its mud being prepared using the composition can be improved the eating for mud during high-pressure slip-casting and starches speed Degree, and can guarantee the physical strength of the green body of thus slurrying, it reduces green body and carries breakage rate.
To reach above-mentioned purpose, the present invention adopts the following technical scheme:
A kind of composition being used to prepare high-pressure slip-casting molding mud, component include: washing by weight percentage China clay 15.3-20%, Guangdong black mud 5.2-5.6%, kaolin 20-23%, porcelain stone 27-29%, calcined kaolin 6-10%, length Stone 16-19%, dolomite 2-2.5%.
A kind of mud that above-mentioned composition is prepared, the mud are made of by weight following component: described 100 parts of composition, 32-37 parts of water.
Chemical analysis after the mud removal Free water includes: SiO by weight percentage261-65%, Al2O3 21-25%, CaO 0.5-1.5%, MgO 0-1%, K2O 2-4%, Na2O 0-1%, Fe2O30-1%, TiO20-0.5%, It burns and loses 6.2-7.2%.
Compared with the existing technology, the beneficial effect of acquirement is technical solutions according to the invention:
1, washing china clay property used in the present invention is illite-structure clay, has preferable plasticity, improves mud The time is split out.
2, due to improving the ratio of kaolin and porcelain stone in formula, it is saturating during high-pressure slip-casting to improve mud It is aqueous.
3, due to joined calcined kaolin in formula, and kaolin is after high-temperature calcination, and internal structure occurs Variation, surface hydrophilic base is destroyed, therefore calcined kaolin and water associativity are weak, can not form moisture film, to promote water Infiltration.Thus the water penetration of mud is improved, improves and eats slurry speed, shorten molding cycle, improve production efficiency.
Although 4, calcined kaolin is able to ascend mud water penetration, slurry speed is eaten in raising, since it is by calcining, molecule Between binding force weaken, cause green body physical strength decline.It is thus necessary to determine that the suitable weight ratio of calcined kaolin is to meet base Body physical strength requirement, guarantee green body in the handling process breakage rate in tolerance interval.In the present invention, calcined kaolin Content accounts for 6%-10% weight percent, that is, improves mud water penetration, improves and eats slurry speed, in turn ensures blank strength.
Specific embodiment
In order to be clearer and more clear technical problems, technical solutions and advantages to be solved, tie below Embodiment is closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only to explain The present invention is not intended to limit the present invention.
The present invention provides a kind of composition for being used to prepare high-pressure slip-casting molding mud, and component is by weight percentage Including washing china clay 15.3-20%, Guangdong black mud 5.2-5.6%, kaolin 20-23%, porcelain stone 27-29%, calcined kaolin 6-10%, feldspar 16-19%, dolomite 2-2.5%.Wherein, the property for washing china clay is illite-structure clay, is had preferable Plasticity improves mud and goes out to split the time.The place of production is Fujian Yongchun Jie's good fortune, and Fujian Ke Fu Materials Co., Ltd may be selected.Kaolin Water-washed kaoline may be selected.It is saturating during high-pressure slip-casting to improve mud for the ratio that calcined kaolin is improved in formula It is aqueous.
It after above-mentioned composition ingredient is complete, then is mixed with water in 1 to 0.35 ratio, is packed into ball mill ball milling, passes through control Amount of water, the amount of trace mineral supplement and Ball-milling Time go out to grind performance are as follows: 370 ± 4 grams/200 milliliters of concentration is glued to control mud V0 is in 140 ± 100 seconds/100 milliliters, residue 4.0 ± 1.5%, granularity≤10 micron accounting 60 ± 3% for property.
Then refine to going out mill mud, cross 100 mesh vibrating screens and by iron remover except after iron again by adjusting aqueous Amount is modulated mud, and 370 ± 3 grams/200 milliliters of concentration, viscosity V0 are obtained after modulation in 60 ± 8 seconds/100 milliliters, viscosity 90 ± 8 seconds/100 milliliters of V30,6 ± 3dny of yield value.
After above-mentioned modulated mud removes Free water, chemical analysis includes: SiO by weight percentage2 61- 65%, Al2O321-25%, CaO 0.5-1.5%, MgO 0-1%, K2O 2-4%, Na2O 0-1%, Fe2O30-1%, TiO20-0.5%, it burns and loses 6.2-7.2%.
We are prepared for 6 groups of samples by the component in table 1, and have carried out high pressure to the mud for using 6 groups of samples to obtain Slip casting forms green body, and tests the parameters of high-pressure slip-casting technique and the physical strength parameter after body drying.Experiment knot Fruit is shown in Table 2:
Table 1: test combinations composition formula
Table 2: each sample high-pressure slip-casting technological parameter test result and green body physical strength test result
As seen from the above table, it joined calcined kaolin in formula, and kaolin is after high-temperature calcination, internal structure It changes, surface hydrophilic base is destroyed, therefore calcined kaolin and water associativity are weak, can not form moisture film, to promote The infiltration of water.Thus the water penetration of mud is improved, improves and eats slurry speed, shorten molding cycle, improve production efficiency.
Although calcined kaolin is able to ascend mud water penetration, slurry speed is eaten in raising, intermolecular since it is by calcining Binding force weakens, and green body physical strength is caused to decline.It is thus necessary to determine that the suitable weight ratio of calcined kaolin is to meet green body Physical strength requirement, guarantee green body in the handling process breakage rate in tolerance interval.
In above-mentioned test, 6# sample calcined kaolin weight ratio is added to 12%, and intensity is then lower than after its body drying 3Mpa carries breakage rate also up to 5.2%, belongs to unacceptable.And 1# sample is not due to plus calcined kaolin, so that eating slurry speed Obviously increase with the shaped high tension time, production efficiency is low.2# sample calcined kaolin ratio is lower, eats slurry speed and shaped high tension Time is still dissatisfied.Therefore, the present invention selects calcined kaolin weight percent for 6%-10%, preferably eats slurry speed to obtain Degree and shaped high tension time, while intensity after preferable body drying can be also obtained, lower carrying breakage rate.
Description above describe the preferred embodiment of the present invention, it is to be understood that the present invention is not limited to above-mentioned implementation Example, and excluding other embodiments should not be regarded as.Enlightenment through the invention, those skilled in the art combine known or existing The change that technology, knowledge are carried out also should be regarded as within the scope of the present invention.
